目的了解苏州市饮用水中邻苯二甲酸酯类(PAEs)的污染情况。方法于2012年1月,采集苏州市水源水,出厂水和管网水。采用气相色谱-质谱联用法(GC-MS)测定水样中PAEs的浓度。结果 TC出厂水检出邻苯二甲酸二甲酯和二甲酸二丁酯,其余未检出。结论苏州饮用水总体情况良好,但在环境形势日益严峻的今天,仍需密切关注太湖和长江水质变化。
Objective To understand the pollution of phthalate esters (PAEs) in drinking water in Suzhou City. Methods In January 2012, Suzhou city water source water, factory water and pipe network water were collected. The concentration of PAEs in water samples was determined by gas chromatography-mass spectrometry (GC-MS). Results TC manufactured water out of dimethyl phthalate and dibutyl ester, the remaining not detected. Conclusions Suzhou drinking water is generally in good condition. However, with the worsening environmental situation, the water quality in the Taihu Lake and the Yangtze River still needs to be closely monitored.
